Referring now more particularly to the several views, and to Fig. 1 in part cular, I have shown the fragmentary outline of a furnace 1 having the grate bars 2 over which is placed a small metal plate 3 on which in turn is placed a small layer of noncombustible material 4 and the latter then covered by a bank of sand. The metal plate 3 is also shaped to form the large central draft pipe 5 through which the air passes to the burner about to be described.

On the top of this bank of sand may be a small layer of cement such as shown at 6,, while firebricks 7 are placed around the interior of the furnace.

Oil supply.

Before describing the burner in particular, reference will be made to the manner of supplying oil to the same, and in Fig. 1 there is shown a supply tank 8 properly supported as at 9, and from this tank a main supply line 10 is shown, a filter 11 being shown in the line near the tank to prevent any of the impurities from reaching the burner. Also, in this main line 10 there is a control valve 12, the line then extending to a nipple 13 tom which is a somewhat larger pi e 14 extending upwardly and is threadec within the nozzle 15 of the burner.

The pipe 14 being larger in diameter than the pipe 10 and the nipple 13 having an internal diameter greater than either of these supply pipes, the oil will slow up in its movement when reaching thenipple and allow any sediment which may have passed the be dropped in a small sump pipe 16 which pipe may be cleaned by removing the cap 17 when necessary.

It is to be understood that the oil supply arrangement asshown at 8 is the one preferred where a large tank may be kept within the cellar, but if the Underwriters laws make it necessary to have thetank in the yard, I may employ a standard type of vacu um system for supplying the necessary 011 to the burner.

\Vithin the main line 10 there is placed the standard form of automatic cut out 18 on which hangs the little bucket 19 so that if the oil should fail to burn, the overflow into the bucket will automatically shut off the main supply.

Base of burner.

Referring now to Figs. 8, 9 and 10 for the moment, there is shown what I term the base of the burner which is properly set over the draft pipe 5, while the cement 6 contacts with and seals the base in its proper position as shown in Figs. 1 and 2.

This base 20 is preferably a dish-shaped iron or steel casting, and in the drawings this is shown as substantially oval, although itmay be made circular in outline if desired. At its opposite ends, in the upper surface are the openings 21, and as may be seen in Figs. 9 and 10, these openings have the upstanding rims or flanges 22 formed thereon for the reception of the ends of a manifold 29 shortly to be described. This base, as mentioned, is dished to form the central basin 23 wl formed the above the lower surface of the basin 23 and also extends below the lower edge of the side rim 25 of the base.

By forming the base of the burner in this manner. a certain amount of oil may be centrally placed within the base. or rather within the chamber 23, and ignited to start the operation of the furnace. To limit the height to which this oil may rise within the chamber, 1 provide an overflow opening 26 which is connected with the pipe 27 which in turn extends to the bucket 19 heretofore referred to. A little cap 28 fits within this opening 26 and is so arranged that oil may flow under this cap and into the opening 26 when the oil reaches the level of the underportion of the cap.

As before n'ientioned, this opening 26 and the automatic cut off valve are for emergency purposes only, so that in case of an accident to the burner or the oil failing to ignite. the main supply pipe will be automatically cut off.

The length of the 'base 20 and the diameter of the draft pipe 5 are so proportioned that the incoming air will flow up through the openin 's 21 in the burner and up into the manifo d 29 as may be seen in several of the figures.

31 anifold.

The manifold 29 is also a steel or iron casting, oblong in shape, its length corresponding to the length of the base 20, but

.within the opening.

its width is much less than the width of the base so that the burning oil within the chamber 23 will pass upwardly and around this manifold to rapidly heat the air within it.

Figures 2 and 3 show respectively a longitudinal and cross section of the manifold, and it will be noticed that the openings 30 at the opposite ends of this manifold are similar in shape to the openings 21 formed in the base, and small cooperating flanges 31 are provided to tightly fit about the flanges 22 of the aforementioned openings 21 of the base 20.

Centrally of the manifold and in its bottom surface, there is formed the opening 32, which opening is elevated with respect to the openings at the respective ends of the manifolds, while the internal shape of the entire manifold is such that it will direct the expanding air to the central opening. About this central opening I provide the plurality of vanes 32 and these vanes may be integral or loose vanes might be properly mounted In either event, they are pitched so. as to direct the heated air to the vanes of a rotor shortly to be described.

To strengthen the manifold throughout its length, I provide a central rib 33 which extends both across the under internal surface of the manifold as wellas across the outer top surface of the manifold. This rib merges with the integral handle on the top of the manifold.-

It will also be noticed that the inner upper surface of the manifold extends downwardly by casting the walls 35 as shown, and the apex of the deflection is directly above the central opening in the bottom of the manifold.

A slightly different form of manifold is shown in Fig. 16 which will be described more in detail as the spccification proceeds.

34 formed Nozzle and rotor.

Refering'now to the aforementioned nozzle 15 and its cooperating parts, it will be seen (Fig. 15) that the nozzle is provided on its outer surface with a plurality of spacer ribs 36 which merge with the integral head 37. This head has a central cut out portion 38 and from its uppermost edge the head slopes gradually downwardly as may be seen at 39 and merges with the circular flange 40.

The nozzle at its lower end is provided with a threaded opening 41 and dropped within the nozzle is a small disc 42 with the holes 43.therein while in the center of the disc is the small pintle or pivot pin 44 on which rotates the shaft 45 of the rotor 46.

Referring again to the nozzle and at the oint where the stem merges with the head, it will be noticed that the head is provided with an annular seat 47 for the repe tion of a nipple 48. This nipple 48 is pro'vi ed with a; cooperating seat 49, an upper body portron 50 and the upper flange 51. This nipple 48 is then placed within the nozzle 15, as may be clearly seen in Fig. 2, and the cut out portion 38 of the nozzle together with he upper portion of the nipple, forms the annular chamber 52, to which water or steam is led by the pipe 53 extending to the bottom of a tank 54. This pipe passes upwardly along the nozzle 15 and between the spaced ribs 36 (Fig. 14) so that the water will be partly. heated as it passes to its annular chamber.

The peripheral nipple 48 is provided with little nitches 55, so that as the water within the chamber 52 is transformed into steam, it may pass outwardly through these little nitches 55 directly beneath the rotor 46. It might be here mentioned that the nozzle 15 fits snugly within the circular hub 24 of the base 20,

the spacer ribs 36 contacting with the side walls of the hub 24 allowing the cool air to pass upwardly about the stem of the nozzle 15.

Fitting within the nipple 48 is the ball race 56, thus providing a ball bearing surface for the shaft 45 near its upper end, while the pintle forms the bearing lower end.

edge of the rim 51 of the i for the A part of the main pipe 14 is threaded within the lower end of the nozzle and the oil flows upwardly through the holes 43 in the disc 42, thus lubricating the pintle 44, and, as the internal diameter of the nipple 48 is greater than the external diameter of the shaft 45, the oil passes upwardly around the shaft, lubricates the ball race 56, and then capillary attraction causes the oil to travel up the hub of the rotor and partly along the under surface of the rotor.

The upper flange 51 of the nipple and the sloping walls 39 of the head 37 of the steam direct any oil which may, in its liquid state drop to fall within the chamber 23 of the base 20 to be burned, rather than allow it to leak back into the nozzle.

Mounted on the top of the stem of the shaft 45 is the heretobefore mentioned rotor 46, and this rotor is preferably a bronze casting consisting of a hub 57 inv which passes the threaded end of the shaft 45.

The body portion 58 of the rotor is disclike in shape and slopes from the hub downwardly and outwardly, its diameter being ill) substantially the diameter of the head of the I ride a plurality of integral vanes 59, which are preferably slightly curved, so that these vanes will cooperate with the vanes 32- in the manifold 29 as heretofore mentioned.

These vanes 59, as may be seen in Figs. 1, 2 and 11. have their outer edges perpendicular to the base of the rotor, while their upper edges present a plane surface so that there is very little space between the upper edges of the vanes and the opening 30 in the manifold. Thus, the full effect is obtained from the air rushing from the manifold to the vanes of the rotor. The shape of the body portion of the rotor is highly important. It will he noticed that there is a gradual slope to the body portion and this is provided so that the oil will not be thrown from the rotor until the oil has reached the outer peripheral edge. The centrifugal force causes the oil to cling to the surface until it has fed to a plane parallel to the peripheral edge of the rotor where it will he released at the highest rate of speed. In actual practice the oil will be seen to ignite about one inch from the edge of the rotor.

Referring now form of rotor and to the slightly modified the central opening of the n'ianifol'd. as shown in Fig. 1G, in this instance. a rotor shaft is threaded within the hub 61 of the rotor. the rotor in this instance being more in the shape of a spear head, that is, the center portion extended upwardly to a point and the slope of the head is much sharper than in the former instance. Likewise the upper edges of the vanes 62 incline sharply towards the apex 63.

The central portion of the manifold has the oppositely arranged openings 64 whilethe dividing walls 65 of these openings incline at an angle similar to the angle of the upper edge of the vanes 62. Similar to the preferred form the cool air will enter the manifold from its opposite end and as the air is heated by the flame, it will he deflected )y the walls 66 centrally of the manifold and pass downwardly through the opening 64.- directly against the vanes 62 of the rotor to cause the same to rotate at a high rate of speed.

Water feed.

Referring for the moment to the tank 51 for supplying the water, there is shown a float valve 67 so that the water in the tank is autonnitically cut oil when it reaches a certain height. I also position a needle valve 68 in this water line, so the amount of water which flows to the annular chamber 52 may be regulated.

This is necessary as the water in the annular chamber 52 and in the small pipe just helow the same, may heat very rapidly and if too much steam should escape from without this chamber, it would interfere with the burning of the oil. As will be appreciated, as

this arrangement of the water and its conversion to steam is to improve the combustion and furthermore is to prevent carbon from forming on the under surface of the rotor and upon the upper flange 51 of the nipple.

If carbon were allowed to-form on the under surface of the rotor or upon the nipple, it, in time, would be so built up that it would interfere with the free rotation of the shaft and. its rotor.

It will be appreciated at this time also that any other similar manner might be used for forcing a jet of steam from the water line to the. under surface of the rotor.

Operation 0 f burner;

The operation of the oil burner isexceedingly simple and the procedure would be substantially as follows The control valve 12 would be turned so that a small amount of oil would be allowed to flow from the main supply line upwardly through the nozzle and collect in the chamber 23 of the base.

' I have not shown any special means of first igniting this oil, although any desired form may be used. In the past a small piece of ragor cloth, or waste is lighted and then thrown into the base 20 and allowed in turn to ignite the oil in the chamber 23.

After the oil has burned for a short time, the air in the manifold 29 becomes heated, expands and moves towards the center of the manifold and downwardly through the central opening 32, and in its passage will be deflected by the vanes 32 and strike the vanes 59 of the rotor 46. The hot air will cause the rotor to at first revolve slowly and then gain in speed until it reaches its maximum rotation. In the meantime, a draft is created upwardly through the pipe 5 to supply the air for the flame and tosupply the air to be heated to the manifold.

After the oil is ignited in the basin, the heat will also cause the oil which has flowed upwardly into the nozzle 15 to rise in temperature and to partly volatilize and this oil of the rotor, causes the oil gasto be thrown outwardly in a whirlmg motion, thus mixing it with the air and readily igniting to burn with a very hot flame.

This flame also surrounds the manifold so a constant source of hot air actuates the rotor. Of course the heatedair mixed with the gas and oil furnishes a nearly perfect combustible fuel. This hot flame is made possible by the preheating of the air to a very high temperature as in reality the mixing of the preheated air causes an explosion of the fuel and air rather than a slow burn- 1ng.-

At the sau'ie time water is being supplied from the tank 54 and as it rises in the pipe line to its annular chamber 52 it becomes heated and escapes as steam against the under side of the rotor to keep the same from carbonizing and also helps the oil to burn with more perfect combustion. By heating the air, using steam and using the rotor, it is possible to use a very low grade of oil with good results.

The control valve 12 may be regulated to provide the desired amount of fuel to the oil burner, tothus regulate the amount of heat from the burner. If for any reason the pipe line should become momentarily stopped up and the flame extinguished, and the oil should then again start to flow, the overflow in the chamber 23 would flow to the little bucket 19 and automatically shut off the fuel supply.

By placing the little ribs 36 about the stem of the nozzle, the cool air may pass upwardly around the nozzle and prevent it from overheating.

If the manifold is designed as shown in Fig. 16, and the rotor is shaped as also shown in this view, the operation will of course be the same as in the preferred form, the purpose in both forms being to utilize to the greatest advantage the heating area of the manifold and the hot air expanding in the manifold to thus supply the oxygen to the fuel and also drive the rotor for the atomization pf the fuel.

If, for any reason, the rotor after months of service should become carbonized on its bottom surface, a bar may be placed under the handle 34: of the manifold and the manifold body removed from the base. The rotor may then be drawn from without its nozzle, quickly cleaned and replaced. The manifold will then be set in its operative position and the oil burner again ready for use.

It will thus be seen that it is but a matter of a few minutes to clean the .burner if itlrecomes necessary and that there is only one moving part in the whole burner which may be cleaned or even replaced if the same should become damaged.

From the foregoing it will be seen that I have provided an extremely simple and efficient form of oil burner consisting primarily of but three parts, to wit, a base, formed of a simple metal casting, a. manifold, another simple form of casting, and a nozzle with a rotor therein. Any of these parts mav berenwcd if they should become worn and any of the parts may be removed if found necessary.

Again, the carbonization of the rotor, and at thesame time, these means, that is, a jet of steam, adds to the combustible mixture.

Finally, by superheating the air the fuel burns more readily and more rapidly, thus fin-ming a more perfect mixture and preventing any soot or odor forming within the furnace.

Many slight changes might be made without in any way departing from the spirit and scope of my invention.

Having thus described the invention, I claim as new and desire to secure by Letters Patent is: p
